looking for PseudoInverse function

I'm engineer of small company. I'm using IPP for Matrix analysis. because IPP is faster and convinient than other lib.

I'm looking for PseudoInverse function. but I couldn't find it.

if not. does anyone use pseudoinverse in IPP? I want to how implement the process

Thanks

Hello,

just to be clear, what do you mean under pseudo inverse operation?

Vladimir

Thanks for reply

Sorry for my stupid english skill :)

Question 1: Does IPP have a pseudo inverse function?

Question 2: If doesn't exist in IPP, How operate pseudo inverse using IPP?

Hi Sagent2,

Are you looking for the function like matlab discription,

/*

PINV(A) produces a matrix X of the same dimensions

as A' so that A*X*A = A, X*A*X = X and A*X and X*A

are Hermitian. The computation is based on SVD(A) and any

singular values less than a tolerance are treated as zero.

The default tolerance is MAX(SIZE(A)) * NORM(A) * EPS(class(A)).

*/

right?

Then IPP haven't direct function, but ipp should be have oneSVD function, you may check it in ippm or ipps manual. Or check IPP's sister library, math kernal library (MKL), which provide more math routines in it.

Regards,

Ying
